Oxidative Stress in Patients before and after On-Pump and Off-Pump Coronary Artery Bypass Grafting: Relationship with Syntax Score

Figure 1

Dynamics of oxidative stress parameters’ changes in CABG, precisely two surgery types, i.e., CPB and OPCAB before surgery and after the procedure in defined study points. (a) Total oxidative status (sTOS), (b) superoxide anion (pO₂^.–), (c) prooxidative-antioxidative balance (sPAB), (d) malondyaldehide (sMDA), (e) total antioxidative status (sTAS), and (f) superoxide-dismutase (pSOD). , , ; 0.01; 0.001 OPCAB vs. the same time point in CPB group. ^{a, aa, aaa}; 0.01; 0.001 in CPB group (t2-t5) vs. baseline. ^{b, bb, bbb}; 0.01; 0.001 in OPCAB group (t2-t5) vs. baseline. s: serum; p: plasma.
